Beach sands from Aggelochori coast line are investigated for their geochemistry and REE content, mineralogy provenance. These fluvial bear heavy minerals enriched horizons (containing such as magnetite, zircon, ilmenite, hematite, rutile titanite) that can be distinguished due to black color formed usually the action of sea waves deposit remove lighter ones. After a suitable processing (washing...

Apatite minerals of I-type Zouzan granitoids and typical garnet-bearing S-type granites have been analyzed by electron microprobe to define trace element concentrations and compare them in different granites. Zouzan granites are composed of apatites with lower Fe, Mn, Na and HREE and higher REE and ∑REE relative to S-type ones. Trace elements abundances of apatite often vary with some parameter...

Abstract The Ruwai skarn deposit is the largest polymetallic in Borneo and located Schwaner Mountains. skarns massive orebodies are hosted marble of Jurassic Ketapang Complex, which was intruded by Cretaceous Sukadana granitoids. prograde-stage garnet retrograde-stage titanite yielded U-Pb ages 97.0 ± 1.8 to 94.2 10.3 Ma 96.0 2.9 95.0 2.0 Ma, respectively. These similar Re-Os obtained on sulfid...

Varietal studies of sedimentary provenance use the properties individual minerals or mineral groups. These are recorded as lists numerical tables that can be difficult to interpret. Multidimensional Scaling (MDS) is a popular multivariate ordination technique for analyzing other types data based on, example, detrital geochronology petrography. Applying MDS varietal would allow them treated on a...

In the Cheshmeh-Bid district of Khajeh-Jamali ophiolitic massifs (Southern Iran), mantle peridotites are intruded by abundant pyroxenite dykes. A few these dykes remarkable for occurrence native copper associated with development a metasomatic reaction zone. The progressively reacted, from their margins towards center, an amphibole + antigorite selvage, followed centimeter-thick clinopyroxene a...

almabulage complex is located in the north of asadabad city, northwestern hamedan province, in sanandaj-sirjan structural zone. the complex includes several types of low-grade metamorphosed rocks with various protoliths as well as two intrusion having different chemical compositions of synogranite and gabbro. the synogranite intrusion rock has perthite and granophyric co-growths textures and au...
